The battle between Noel and the supreme devil and the third prince was something beyond anyone's imagination.
A single slash from them was enough to destroy the entire wall, even with their protection. There were countless sword marks on the ground. The demon king was in the form of a beast in the past, but that was the reason he lost.
As a result, he had become a human to find a way to fight another human by understanding them. It included an understanding of the sword.
Due to his memory as the demon king as well as the experience of fighting Alex, the demon king's attainment in the way of the swords was incredibly high.
In fact, it looked like he was on par with Noel. On the other hand, the supreme devil, as the disciple of Alex, had sword skills that surpassed Noel.
He might have been outshined by the Sword Saint, but he could be the third strongest, especially with all the experience he had accumulated over the past one thousand years.
